Not to beat a dead-horse, but the age of the sword is over. You know why the Samurai no longer exist? It's because 10 farmers with rifles and 5 days training could easily kill 50 Samurai that spent decades training. The Japanese don't employ samurai or go around with swords. The Banzai charge used in WW2 worked against the Chinese (who had very old rifles), but was completely useless against the Americans who had 50. cal Machine guns.
No modern military uses swords in combat. Officers are still issued with ceremonial swords, but in combat they are issued with knives and bayonets.
Katanas were good for their time, as were swords, but they serve no practical purpose whatsoever. Like a giant suit of European armor, a Japanese sword is absolutely useless, and a sign of a defeated and outmoded military weapon.
I get the fact that some practice sword fighting for the skill and for the exercise - that's cool, and fine and probably healthy. But unless you are considering such a sport, why bother? I suppose I just don't understand the "Collector" mentality (which my father has) of collecting things I'm never going to use. Ever. My father collects old binoculars and cameras that, half the time, don't even work. They just sit there, and he has lost all interest in them (doesn't stop him from getting new old cameras though).
So don't get one. It's a waste of money. I'm sure you have bills, college loans, basic necessities that need buying and all that stuff. And even if you don't, put it in a bank. Save up. Buy insurance.
Be responsible.
